Material selectionWhat Specialty Materials Work Best for Hydraulic Components?

  • Carbon Steel
  • Stainless Steel and Specialty Steel
  • Aluminum Alloys
  • Copper Alloys

Carbon Steel

Carbon steel can be found both in the Hydraulic valve and the Pneumatic pump. Some examples are barrels, valves, blocks, distributors, cylinders, and the like. Its decorative uses may also range from wheel rims, covers, screws, washers, bolts, nuts, fasteners, and the like. All of these are essential in maintaining the structure and stability of any given fluid and air system.

Below are some of the grades in stock:
AISI 1018
AISI 1045
AISI 1144
AISI 1215
AISI 12L14
AISI 4130
AISI 4140
AISI 8620

Stainless Steel and Specialty Steel 

Stainless steel alloys have found increasing usage in Hydraulic and Pneumatic components that require great strength but can handle the increased weight. The high corrosion and temperature resistance found in stainless steel make it suitable for a range of fluid and air systems.

Below are some of the grades in stock:
AISI 303
AISI 304
AISI 316
AISI 630

Aluminum Alloys

There is a great deal of aluminum alloys in the Valve and Pump. Most aluminum alloys offer high weight to strength ratios, corrosion resistance, formability, and favorable pricing.

Below are some of the grades in stock:
Aluminum 2011
Aluminum 4032
Aluminum 6061
Aluminum 6063
Aluminum 7075-T7651

Copper Alloys

Copper has high levels of strength, conductivity, and resistance to corrosion. In particular, the resistance to corrosion is an important trait for valves.

Below are some of the grades in stock:
Copper C3600
Copper C3602
Copper C3604
Copper C4926 (Lead Free)
